Struct sysinfo::System

pub struct System { /* fields omitted */ }

Structs containing system's information.

Trait Implementations

impl Debug for System

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for System

fn default() -> System

Returns the "default value" for a type.

impl SystemExt for System

fn new_with_specifics(refreshes: RefreshKind) -> System

Creates a new [System] instance and refresh the data corresponding to the given RefreshKind.

fn refresh_components_list(&mut self)

Refresh components list.

fn refresh_memory(&mut self)

Refresh RAM and SWAP usage.

fn refresh_cpu(&mut self)

Refresh CPU usage.

fn refresh_processes(&mut self)

Get all processes and update their information.

fn refresh_process(&mut self, pid: Pid) -> bool

Refresh only the process corresponding to pid. Returns false if the process doesn't exist. If it isn't listed yet, it'll be added.

fn refresh_disks_list(&mut self)

The disk list will be emptied then completely recomputed.

fn get_processes(&self) -> &HashMap<Pid, Process>

Returns the process list.

fn get_process(&self, pid: Pid) -> Option<&Process>

Returns the process corresponding to the given pid or None if no such process exists.

fn get_networks(&self) -> &Networks

Returns network interfaces.

fn get_networks_mut(&mut self) -> &mut Networks

Returns a mutable access to network interfaces.

fn get_global_processor_info(&self) -> &Processor

Returns "global" processors information (aka the addition of all the processors).

fn get_processors(&self) -> &[Processor]

Returns the list of the processors.

fn get_total_memory(&self) -> u64

Returns total RAM size in KiB.

fn get_free_memory(&self) -> u64

Returns free RAM size in KiB.

fn get_used_memory(&self) -> u64

Returns used RAM size in KiB.

fn get_total_swap(&self) -> u64

Returns SWAP size in KiB.

fn get_free_swap(&self) -> u64

Returns free SWAP size in KiB.

fn get_used_swap(&self) -> u64

Returns used SWAP size in KiB.

fn get_components(&self) -> &[Component]

Returns components list.

fn get_components_mut(&mut self) -> &mut [Component]

Returns components list.

fn get_disks(&self) -> &[Disk]

Returns disks' list.

fn get_disks_mut(&mut self) -> &mut [Disk]

Returns disks' list.

fn get_uptime(&self) -> u64

Returns system uptime.

fn get_load_average(&self) -> LoadAvg

Returns the system load average value.

fn new() -> Self

Creates a new [System] instance with nothing loaded except the processors list. If you want to load components, network interfaces or the disks, you'll have to use the refresh_*_list methods. SystemExt::refresh_networks_list for example.

fn new_all() -> Self

Creates a new [System] instance with everything loaded.

fn refresh_specifics(&mut self, refreshes: RefreshKind)

Refreshes according to the given RefreshKind. It calls the corresponding "refresh_" methods.

fn refresh_system(&mut self)

Refresh system information (such as memory, swap, CPU usage and components' temperature).

fn refresh_components(&mut self)

Refresh components' temperature.

fn refresh_disks(&mut self)

Refreshes the listed disks' information.

fn refresh_networks(&mut self)

Refresh networks data.

fn refresh_networks_list(&mut self)

The network list will be updated: removing not existing anymore interfaces and adding new ones.

fn refresh_all(&mut self)

Refreshes all system, processes, disks and network interfaces information.

fn get_process_by_name(&self, name: &str) -> Vec<&Process>

Returns a list of process containing the given name.
